Yeah, laptops usually don't have upgradeable parts other than RAM and HDD, sometimes CPU but you have to tear the whole thing down to get to it. Graphics chips, as well as most other peripheral devices like sound, network, USB, modem, etc, are usually soldered right on to the motherboard, making it impossible to replace. Some laptops have the graphics on a separate board, but these boards are manufacturer-specific, so you couldn't upgrade yourself. I agree that there needs to be some standardization in laptops. A small form factor graphics card and connector needs to be developed so that laptop graphics could be upgraded. Also remember that laptops have limited cooling, and a desktop replacement laptop will put out as much heat as the equivalent desktop, but with much less cooling. My temperatures run really high on my relatively low end 8600M GS, 2 8800M's in SLi would run incredibly hot and you'll probably need some sort of cooling.
